Celiac.com 09/21/2023 - Gluten sensitivity is a chronic intolerance to gluten in people who have a genetic predisposition. It is thought to involve the immune system and can lead to various skin conditions. Celiac disease is one common form of gluten intolerance and can affect not only the digestive system but also the skin, endocrine system, nervous system, and blood. We know that a number of skin disorders are associated with celiac disease. Psoriasis, a chronic inflammatory skin condition, has shown improvement when individuals adopt a gluten-free diet. Specifically, palmoplantar pustulosis, a variant of psoriasis, and aphthous stomatitis, which causes recurring mouth ulcers, have responded positively to gluten elimination. Dermatitis herpetiformis, another skin disorder related to celiac disease genetically, has also seen significant improvement with a gluten-free diet. However, atopic dermatitis, another prevalent long-term skin condition, has produced inconsistent results with gluten removal. Further research is needed to draw more definitive conclusions. Hereditary angioedema has shown an association with gluten intolerance in some cases, with symptomatic benefits observed after adopting a gluten-free diet. Vitiligo and linear IgA bullous dermatosis have also shown clinical evidence of improvement with a gluten-free diet. On the contrary, rosacea, a skin condition causing facial redness, has been linked to an increased risk of developing celiac disease. The Research Team A team of researchers recently set out to examine the association between gluten intolerance and skin disorders. The research team included Vaibhav Vats, Pallavi Makineni, Sarah Hemaida, Anum Haider, Sachin Subramani, Navjot Kaur, Amna Naveed Butt, Renee Scott-Emuakpor, Mohammad Zahir, Midhun Mathew, and Javed Iqbal. They include one Physician, Istanbul Okan University, Istanbul, TUR; and are otherwise variously affiliated with the department of Internal Medicine, Smt. Kashibai Navale Medical College & General Hospital, Mumbai, IND; the department of Neurosurgery, Mayo Hospital, Lahore, Pakistan; the department of Medicine/internal medicine, Allama Iqbal Medical College, Lahore, PAK; the Department of Internal Medicine, Pennsylvania Hospital, Philadelphia, USA; the department of Medicine, Ayub Medical College, Abottabad, Pakistan, Abottabad , PAK; the department Dermatology, University of Miami Miller School of Medicine, Miami, USA; the department of Medicine, Government Medical College, Amritsar, Amritsar, IND; the department of Internal medicine, ESIC medical college and hospital, Gulbarga, IND; the department of Internal medicine, Img helping hand, Karachi, PAK; and the department of Medicine, All India Institute of Medical Sciences, Bhubaneswar, Bhubaneswar, IND. Their review highlights the potential impact of gluten intolerance on various skin conditions and the potential therapeutic benefits of a gluten-free diet for managing symptoms. However, more clinical trials and observational studies are needed to fully understand the underlying mechanisms and provide definitive dietary recommendations for these conditions.

Celiac.com 03/30/2023 - A study recently published in the Journal of the American Academy of Dermatology shows that people with psoriasis have twice the odds of having celiac disease compared to those without psoriasis. The study is the work of a research team that included Marina Z. Joel, BS; Ryan Fan, BA; and Jeffrey M. Cohen, MD. They are variously affiliated with the Johns Hopkins University School of Medicine, Baltimore, Maryland; the Yale School of Medicine, and the Department of Dermatology at Yale School of Medicine, New Haven, Connecticut. The Psoriasis & Celiac Disease Study For their study, the Ms. Joel and her colleagues examined the association between psoriasis and celiac disease. They used data from 316,166 adults, and found that of the 6,476 patients with psoriasis, 1.65% had celiac disease compared to nearly 0.5% of 309,690 patients without psoriasis. The study controlled for various factors such as age, sex, race and ethnicity, smoking status, autoimmune diseases linked to psoriasis and celiac disease, and body mass index (BMI), and found that psoriasis remained significantly associated with celiac disease. Study Findings The authors note that while the exact mechanism behind this association is unclear, genome-wide association studies have found that many susceptibility loci for psoriasis overlap with those for celiac disease: “While the pathophysiologic mechanism behind the association between psoriasis and celiac disease is unclear, several explanations have been proposed. Genome-wide association studies have found that many susceptibility loci for psoriasis overlap with those for celiac disease," they write. They add that "both psoriasis and celiac disease are T-cell driven disorders, there could be shared immunogenic mechanisms between the two conditions." Although more research is needed to fully understand the link between psoriasis and celiac disease, studies that help to document connections between celiac disease and other disorders are very helpful in clarifying the overall celiac disease puzzle.

Celiac.com 01/09/2023 - Psoriasis is one of several skin conditions long associated with celiac disease. Several studies have found connections between psoriasis and celiac disease, but so far no study has shown a causal connection between these two autoimmune conditions. A new study shows that celiac disease patients face a higher risk of psoriasis, but not vice versa. Here's what they found. Genetic Study A team of researchers recently set out to explore the causal link between psoriasis and celiac disease with bidirectional 2-sample Mendelian Randomization (MR) study. The research team included Lin Li, Lixin Fu, Liwen Zhang & Yanyan Feng. They are affiliated with theDepartment of Dermatology, Chengdu Second People’s Hospital, Chengdu, Sichuan, China. The Psoriasis-Celiac Disease Connection The team set out to extract eligible instrument variables with genome-wide significance. To do so, the team used data from the published genome-wide association studies (GWAS) of the European population. They then performed sensitivity, post-MR, and inverse variance weighted (IVW) analyses. The MR analyses showed that genetically doubling the odds of celiac disease would increase the risk for psoriasis. Subsequent sensitivity analyses reinforced those results. Higher Psoriasis Risk for Celiac Patients However, the team's data showed that genetically determined psoriasis was not connected with the risk for celiac disease. This study offers new genetic evidence that celiac patients face an increased risk of psoriasis, while psoriasis patients face no higher celiac risk. For this reason, the team advises clinicians to be aware of the connections, and to closely watch for any psoriasis-associated skin symptoms in celiac patients, or in patients with celiac symptoms. This study offers another valuable insight into the many connections between celiac disease and the risk of other auto-immune conditions, and perhaps supports the idea that all non-genetically determined psoriasis patients should be screened for celiac disease.

Celiac.com 12/16/2019 - Psoriasis is a skin condition associated with several immune-mediated inflammatory diseases, including celiac disease. Currently, however, researchers don't have much solid information regarding the chronology of psoriasis development. A team of researchers recently set out to investigate the chronology of immune-mediated inflammatory diseases relative to psoriasis. The research team included Yuki M.F. Andersen, MD, PhD, Jashin J. Wu, MD, Jacob P. Thyssen, MD, PhD, DMS, and Alexander Egeberg, MD, PhD. They are variously affiliated with the Department of Dermatology and Allergy, Herlev and Gentofte Hospital, University of Copenhagen, Copenhagen, Denmark; the Dermatology Research and Education Foundation, Irvine, California; and the Department of Dermatology and Allergy, Herlev and Gentofte Hospital, University of Copenhagen, Copenhagen, Denmark. The team reviewed data from Danish nationwide administrative registries to examine the occurrence of immune-mediated inflammatory diseases in 10,923 patients with psoriasis, and in 109,230 control subjects from the general population. They found that about 20% of psoriasis patients developed one or more immune-mediated inflammatory diseases, with risk that is five times greater than in the general population. Most patients received a diagnosis of immune-mediated inflammatory disease, except for psoriatic arthritis, before being diagnosed with psoriasis. Psoriasis patients were far more likely to have multiple immune-mediated inflammatory diseases. They were also far more likely to have human leukocyte antigen B27 positivity. This study was limited by the unavailability of clinical measurements. Still, the data show that immune-mediated inflammatory diseases are common in patients with psoriasis, and are usually diagnosed before psoriasis. This information could help researchers to better understand the factors influencing the development of psoriasis. Read more in the Journal of the American Academy of Dermatology

Celiac.com 01/30/2018 - Numerous clinicians have reported higher levels of celiac disease markers in their patients with psoriasis. A number of researchers believe that some psoriasis patients suffer from asymptomatic celiac disease, and a number of patients have reported symptom improvements with gluten-free diets. A team of researchers recently set out to determine the prevalence of antigliadin IgA antibodies in psoriasis vulgaris, and to assess the response of seropositive patients to a gluten-free diet. The research team included Nikolai A Kolchak, Maria K Tetarnikova, Maria S Theodoropoulou, Alexandra P Michalopoulou, and Demetrios S Theodoropoulos. They are variously affiliated with the Department of Hematology, Omsk State Medical Academy, Omsk, Russia; Dermatology Private Practice, Chelyabinsk, Russia; Department of Pharmacy, Trikala General Hospital, Trikala, Greece; Department of Philosophy and Social Studies, School of Philosophy, University of Crete, Rethymnon, Greece; and Allergy Associates of La Crosse, Onalaska, WI, USA. The team assessed the prevalence of gliadin IgA antibodies among patients with psoriasis in an urban population, along with noting the clinical effects of a strict gluten-free diet. The team recruited 97 patients with Psoriasis Area and Severity Index greater than 2.4 from a dermatology clinic. They measured gliadin IgA antibodies in all participants and in 91 control subjects. They found elevated gliadin IgA antibodies in 13 patients, and two controls. All 13 patients were placed on a strict gluten-free diet without any other modifications in their ongoing treatment of psoriasis. Psoriasis patients who do not have celiac disease or non-celiac gluten sensitivity commonly show high levels of antigliadin IgA antibody. These results show that antigliadin IgA testing can identify psoriasis patients likely to benefit from a gluten-free diet. Source: Journal of Multidisciplinary Healthcare.

Celiac.com 05/19/2012 - Because a number of past studies examining the connection between celiac disease and psoriasis have had contradictory findings, researchers wanted to get a better idea of the actual risk of psoriasis in patients with biopsy-verified celiac disease. The researchers were J.F. Ludvigsson, B. Lindelöf, F. Zingone, and C. Ciacci, with the Department of Pediatrics at Sweden's Örebro University Hospital. For their study, they used data from 28 pathology departments in Sweden to identified individuals with celiac disease diagnosed between 1969 and 2008. They found 28,958 patients with Marsh 3 villous atrophy. They then used Cox regression to compare those celiac disease patients with 143,910 sex- and age-matched control subjects, and to assess the risk of psoriasis. They found that celiac disease was a risk factor for future psoriasis (hazard ratio (HR) = 1.72; 95% confidence interval (CI) = 1.54-1.92. They found that, during follow-up, 401 individuals with celiac disease and 1,139 controls were diagnosed with psoriasis. They found that the absolute risk of future psoriasis in patients with celiac disease was 135 per 100,000 person-years, with an excess risk of 57 cases per 100,000 person years. Overall, 42% of the cases of psoriasis in patients with celiac disease could be attributed to celiac disease. Moreover, in children the team saw a strong association between celiac disease and psoriasis (HR = 2.05; 95% CI = 1.62-2.60). Their results show that the connection between celiac disease and psoriasis seems to be far more than coincidental, as we also found a positive association between celiac disease and psoriasis before celiac diagnosis, with an odds ratio of 1.91; 95% CI = 1.58-2.31). They conclude that individuals with celiac disease do, in fact, face an increased risk of psoriasis both before and after celiac diagnosis.

Celiac.com 07/29/2010 - The underlying causes of psoriasis are not well understood. Many patients with psoriasis also have a sensitivity to gluten. In an effort to better understand any connection between psoriasis, celiac disease, and the HLA Cw6 genotype, a research team examined the expression of celiac-associated antibodies gliadin IgA, gliadin IgG, and tissue transglutaminase IgA, and possible associations the antibodies may have with the HLA Cw6 gene in people with psoriasis. The team included Sangeeta Singh, Gyanendra Kumar Sonkar, Usha, and Sanjay Singh. They are variously affiliated with the Division of Immunopathology in the Department of Pathology at the Institute of Medical Sciences, the Department of Dermatology and Venereology, and the Academic Staff College at Banaras Hindu University in Varanasi, India. Antigens are substances that are recognized by the immune system and trigger an immune reaction. Class I human histocompatibility (HLA) antigens are coded into a small cluster of structural genes at the C locus on chromosome 6. They show substantially lower immune-triggering action than the HLA-A and -B determinants, and so are not a major factor in medical donations. Researchers find them useful because of their high-risk association with certain diseases, such as spondylarthritis, psoriasis, multiple myeloma. About 50 percent of all psoriasis patients carry HLC-Cw6. For the study the team evaluated 56 patients with psoriasis, along with 60 healthy control subjects. The team used ELISA to measure antibody levels, and the microcytotoxicity method to type HLA Cw6. Blood samples of psoriasis patients showed significant HLA Cw6 expression compared with control subjects (P Psoriasis patients showed substantially higher celiac-associated antibodies for gliadin IgA/IgG and tissue transglutaminase IgA compared with control subjects (P Women showed substantially higher serum anti-tissue transglutaminase IgA (anti tTG IgA) than did men. Older patients showed higher expressions than did their younger counterparts. Antibodies showed significant positive correlation (anti-gliadin IgA with anti-gliadin IgG: r=0.67, P. From their results, the team concludes that patients with psoriasis commonly show latent celiac disease or celiac-associated antibodies, but that HLA Cw6 is not connected with expression of these antibodies in patients with psoriasis.
